Resistive Random Access Memory (ReRAM) is a type of non-volatile memory that operates by changing the resistance across a dielectric solid-state material. ReRAM utilizes the principles of resistive switching to store data, making it a promising candidate for future
memory technologies due to its scalability, low power consumption, and high speed.
ReRAM operates on the basic principle of resistive switching. This involves applying a voltage to a dielectric material, which causes a change in its resistance. The material can switch between a high-resistance state (HRS) and a low-resistance state (LRS), representing binary data (0 and 1). The changes in resistance are non-volatile, meaning the data remains stored even when the power is turned off. The mechanisms behind resistive switching often involve the formation and rupture of conductive filaments within the material.
Key Advantages of ReRAM
ReRAM offers several advantages over traditional memory technologies such as DRAM and Flash memory. Some key benefits include:
